SMOKE-FILTER FOR PIPES AND CIGARETil'ES.

SPECIFICATION forming part of Letters Patent No. 253,296, dated February'7, 1882.

Applicationled NovembcrQS, 18131. (No model.) i

To all whom fitmay concern Be it known-that I, FRANQIS S. KINNEY, acitizenl of the United States, residing in the city ofNew Brighton,county ofRichmond, and

State of New York, have invented certain new and useful Improvements inSmoke-Filters for Pipes, Cigars, Cigarettes, 85e., fully described andrepresented in-the following specification and the accompanyingdrawings, forming a 1o part of the same.

It is well known that the nicotine taken into the system in smokingtobacco is highly injurious to health, and pipes, cigars, cigarettes,&c., have from time to time been provided with devices intended toprevent the passage of this noxious oil into the mouth of the smoker;but the expedients adopted have,l however, in practice provedinetlicient and unsatisfactory. Among other ways, it has been attemptedto zo rid the smoke of this injurious element bycausing it to passthrough a loose plug or ball of raw cotton interposed between thetobacco and the mouth-piece of a cigarette, but this did not provee'ective and satisfactory. The 2 5 cotton only detained a part of thenicotine, an'd it was also found that slight filaments were drawn intothe mouth, to the great annoyance of the smoker.

It is the object of this invention to provide 3o a complete remedy forthis evil; and to this end I have produced a smoke-lter for pipes,cigars, cigarettes, and the like smoking ai ticles, which primarilyconsists of some substance having chemical properties which cause it totake up, 3 5 neutralize, or destroy the nicotine, thus purifyingthe'smoke and rendering it innoxious and pleasant. There are varioussubstances having qualities which adapt them to this use. Among the moreeffective ones for the purpose 4o are charcoal, tea, coffee, benzoicacid, arsenic ofsoda,lichen from Iceland, and balsam of tolu.

Others, however, having the properties stated,

and an additional one which gives perfume to the smoke, may be'used.These substances, either singly or in any approved combination, are bythe useiot' a proper vehicle made into wafers, balls, or other shapesuitable to the object sought. The filter thus made fis used inconnection with a pipe, cigar, cigarette, or 5o like smoking article insuch manner that the .smoke is caused to-pass through it, in whichpassage the nicotine is taken up, neutralized, or destroyed, and thesmoke, it may be, perfumed. An appropriate and effective vehicle fer thevarious substances named is ordinary cotton or other similar filamentousmaterial, though fine sponge or spongy material of any kind will servethe.purpose well, as will also, with some of the substances named, manyot' the gums, their use being to unite granulated particles of thesubstances into suitable shape in such manner as to permit the smoke topass freely.

lt is to be remarked that cotton, when satu-` rated or treated with oneor more of the substances named, willhaveits filaments so held thatthey7 will not readily detach and be drawn into the. m 011th ofthesmoker, while the chemical properties of the substance with which thecot` ton is treated will cause the filter thus constructed to actreadily upon the nicotine and other alkaloids contained in the smoke, sothat these injurious elements will be entirely eradicated and the smokerendered pure and wholesome.

The accompanying drawings illustrate some of the various ways in whichthis invention may be applied to cigarettes, cigars, pipes, &c.

In said drawings, Figure lshows perspective views of two forms offilter. Figs. 2 and 3 show two dierent ways of applying the iilter to acigarette having one of the glass, paper, or cork mouth-pieces in commonuse. shows another way of applying the filter to a cigarette, with acork or wood mouth-piece. Figs. 5, 6, and 7 show ways of using the lterwith different st vles of detachable mouthpieces, and Fig.8 shows howthe iilterY may be used with a pipe. Fig. 9 shows how the iilter may beapplied to the draft end of.' an ordinary cigarette or cigar.TheilterAmaybemadeofcottonorotherlike filamentous material, saturatedwith some one of the substances hereinbefore named, or with somesubstance having the same chemical properties. The saturation is welleffected by finely powdering the substance and making it into a paste ofproper consistency, then spreading the cotton in 'a very thin layer andsoaking it in said paste, and finally rolling the cotton into 4propershape for the filter. It', however, the

substance is granulated, as can be well done Fig. 4

IOO

` wini coffee, tea, and the nkmhe filter may be made of a properquantity of thesubstance, molded, and retained in form by a suitablecement or gum. Both forms of filter are shown in Fig. 1. One of thesefilters is then interposed between the tobacco and the point where thesmoke issues from the rnouthepiecaasinf` Figs. 2 to 6, where thecigarette or cigar is marked B and the holder C.

In Fig. 2 the filter is placed between the cigarette and the holder, andthe whole secured to ether by the encircling band or strip a.

end of the mouth-piece andthe end of the cigarette, where it is securedin place by pasting 'the project-ing end Z1 of the wrapper onto the bodyof the mouthpiece.

Fig. 4 shows acork or wood mouth-piece, recessed at one end to form achamber for the `reception of the filter, the partsbeing securedv in themanner shown in Fig. 2.

Fig. 5 shows a detachable mouth-piececom posed of a thin shell of glassor other material, into which the filter may be inserted.

Fig. 6 lshowsan ordinary cigar-holder provided with an elongated recess,so. as to provide a seat for the filter back of the cigar.

Fig. 7 shows a cigar or cigarette hold er made in two partsunited byascrew or friction-joint, a chamber being found for the tilter just backof this join-t. Y p Fig. 8 shows a pipe made so'as lto receive a filter,the stem being made with anenlarge.- ment, in which is `a cavity toreceive theiilter.

The stem is divided throughth'e center bf the enlargement, and the partsheld together by a screw-joint. can be inserted, and whenuntitibrifurtherfuse it can be removed. v

One of theseiilters maybe placed-at the draft f end of a cigarette orcigar and confined in placeby the wrapper, as is illustrated inFig. 9.

It is my intention to make these filters as aseparate anticle ofmanufacture, to be used in connection with pipes and detachable cigarand cigarette holders, as show n in Figs. 5, 6, 7, and
